To all whom it concern:

Be it known that I, CLYDE W. Pnmnn'rr, a citizen of the United States, and a resident of Winterset, in the county of Madison and" Stateof Iowa, have invented a certain new and useful Concrete and. Wood Floor Construction Device, of which the following is he object of my invention is to a concrete and woodfloor construction device of simple and inexpensive construction.

Considerable difiiculty is involved in laying a wood floor on a concrete base, and it is my purpose to provide a construction, wh'ereby such a floor can be laid on a concrete base with the parts accurately placed in the proper position amd at a minimum ex- I nse. With these and other objects in view, my

invention consists in the construction, ar-

rangement and combination of the various parts of my device, whereby the objects contemplated are attained,'as1hereinafter more to set. forth, pointed out in my claims, and illustrated in the accompanying drawin? in which: igure 1 shows a tive view of a. floor construction em my invention.

means for fastening the sleepers to the con- Fi .8 shows a similar view illustrating e arrangement of thefastenin devices for shipping. and storage and or conafter installation in the concrete prior to the laying of the wood floor. Ordinarily in laying a wood oo'ncrete'base, the concrete base is laid, then sleepers are. laced in sition on the floor and ancho from t e ceiling, so as to hold them in place. driven into the slee rs, which have preferably one beveled slde'edge, and an additional layer of thin concrete is poured v tween the sleepers for anchoring them.

For faste I have provi dgd This is a slow and expensive proces, which I have sou ht to avoid by means of my structure hereln set forth.

In the accompanying drawings, I have used the reference numeral 10 to indicate generally a co'ncrete'base. Properly spaced on the concrete base are sleepers-11.

the sleepers 11 to the base, the following means:

provide.

in' Figure 3.

detail, sectional, ying Figure 2 shows a perspective view of the Nails or the like are I provide a stri of metal, which is bent to form acentra horizontal member 12,.

from which there extend downwardly convenience after installation in the concrete base and before the slee ers are placed on such base, the ends 0 are nt over the member 12 and overlap each other,

When the concrete base 10 is laid, and

arms or portions 13, the lower parts of which are crimped, as illustrated at A. From the" while the concrete is still soft, the ends A the fastening devices until such time it is desired to lay the wood floors.

At the proper time, the ends C are bent up to vertical 'positi'on,-as shown in and B are forced down into the concrete, as

2, from their positions shown in fulllines in Figure 3, and the sleepers 11 are laid be- 7 tween the spaced and members 0, as shown in Figure 1, and secured thereto by means of nails driven through the holes 14 into the sleepers. 7 Y

By the use of the term crimped'herein,

I intend to include corrugations or any .form

of device having projecting elements for accomplishing proper anchoring; in the concrete. The sleepers will thus be accurately placed and rigidly held in position with relation to the base 10. The flooring may he then nailed to the. sleepers in the ordinary way.

By the construction herein shown, it will be seen that I am enabled to accurately and rigidly place the sleepers. in proper pos ,tion with relation to the concrete base with a minimum of labor and expense.

I am able to avoid the anchoring of the sleepers, which is necessary under the old process, which is expensive-and involves the use of great care to prevent the slipping of the sleepers from their proper position,

and I save the use of material necessary to provide a layer of concrete extending from I g the base part way up the sleepers 11.

I' also greatl reduce the weight of the concrete base, t ereby making it possible to use less material and lighter steel through the entire construction, where a building of several stories is under construction.

It will be seen that my process involves the pouring of a concrete base, the forcing therein while soft of the fastening device,

having the member 12, which serves as a stop member, the allowing of the concrete to set, the laying of the sleepers and fas-' tening them to the fastening devices, and the laying of the floor on the sleepers.

Changes may be made in the details of the construction of myfloor structure and in the practice. of myv process, without departing from the spirit and purpose of my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical e uivalents, or any variations in the steps 0 the process, which may be included within their scope.

I claim as my invention:

1. A support for concrete and wood floor construction, comprising a single piece of material bent to form a central member, downwardly extending parts at the ends thereof for insertion into'a concrete bed, the

ends of the downwardly extending parts 7 being re-bent upwardly and projecting u wardly above said central members, for t e purpose of receiving a sleeper between them.

2. In a device of the class described, a fastener device comprising a single strip of material having a central member with bent down parts for insertion into a concrete bed, crin; and re-bent upwardly from the lower en 's' of the bent down parts, and

projecting upwardly above said central' member to receive a sleeper between them,

and

insertion into the concrete an ecting upwardly above said central memr andprovided with openings for fastening, said last described parts being made of material, which can be bent over said central membeigfor reducing the bulk of said device for transportation and storage.

4. A clip comprising a body portion adapted to rest upon the surface of a concrete bed, downwardly extendin prongs for disposed, permanently attached extensions .for embracing a sleeper. i

5. A clip comprising a body portion adapted to' rest upon the surface of a con crete bed, downwardly extended prongs for insertion into the concrete; and oppositely disposed I extensions adapted to be folded into substantial alignment with the surface of the concrete bed and when vertically extended to embrace the sides of a sleeper.

oppositely I 6. In a floor structure, a concrete bed, Q

rows of aligned sleeper engaging clips, each comprising a body portion adapted to rest upon the surface of the concrete bed, downwardiy extended prongs, inserted in the concrete,1and oppositely disposed, permanently attached vertical extensions, sleepers disposed upon said body portions and between the extensions of therespective clips, and a wooden floor laid on said sleepers.
